Effects of organochlorine exposure on male reproductive disorders in an electronic waste area of South China.

Several studies suggest that organochlorine exposure can affect male reproductive functions, causing poor semen quality, endocrine disruption, or dysregulation of thyroid hormones. This study uses multiple linear regression (MLR) models to analyze the correlation between male reproductive functions and polychlorinated biphenyl (PCBs) congeners or p,p'-DDE levels in serum, semen, and indoor dust samples. Multiple comparisons were all adjusted using the false discovery rate (FDR).

Levels and congener profiles of halogenated persistent organic pollutants in human serum and semen at an e-waste area in South China.

Typical halogenated persistent organic pollutants (Hal-POPs), including polybrominated diphenyl ethers (PBDEs), polybrominated biphenyls (PBBs), polychlorinated biphenyls (PCBs), and dichlorodiphenyltrichloroethane (DDT), are a group of ubiquitous organic pollutants with an endocrine disrupting effect. This study evaluated the accumulation and congener profiles of Hal-POPs in the bodies of men who live/work in areas of South China where electronic wastes are collected and managed, especially in their semen samples. The results show that the detection frequency and serum concentrations of Hal-POP congeners within the high-exposure group (HEG) were higher than those of the low-exposure group (LEG).

[Pregnancy outcome in a woman with premature ovarian insufficiency complicated by systemic lupus erythematosus during pregnancy: a case report].

We report a case of in vitro fertilization and embryo transfer (IVF?ET) with oocyte donation in a woman with premature ovarian insufficiency (POI) complicated by systemic lupus erythematosus (SLE) during pregnancy. The patient had a diagnosis of POI 4 years earlier and 11 weeks after successful pregnancy by IVF?ET with oocyte donation in 2003, she presented with facial edema, and further examinations confirmed the diagnosis of lupus nephritis. She received treatment with prednisone to control the activity of SLE and aspirin and low?molecular?weight heparin to improve placental blood flow with close monitoring of gravida and fetus throughout pregnancy.

[Successful pregnancy following intracytoplasmic sperm injection?embryo transfer in a patient with premature ovarian insufficiency: a case report].

We report a case of ovarian function fluctuation during long-term follow-up in a patient with premature ovarian insufficiency (POI). The patient finally obtained clinical pregnancy with subsequent uneventful full-term delivery after several intracytoplasmic sperm injection-embryo transfer (ICSI-ET) cycles. This case demonstrates that hormone replacement therapy (HRT) and assisted reproductive therapy should be applied as soon as possible to young patients with POI who have a strong desire for pregnancy in the absence of contraindications.
